Leader Prometheus shook his head, "Aiyintan, under normal circumstances, I believe New Human Civilization would be happy to accept this cooperation... Level 5 Civilization's genetic memory technology, although elusive and with a slim chance of success, a joint effort might just solve it? This isn't something that can be measured by Amoeba Points, it's a shortcut to becoming a Level 5 Civilization."
"But now..."
"We are merely a Third-level Civilization, and they are merely a Fourth-level Civilization, lacking thorough research on self-awareness. I think they would tend to self-preserve and wouldn't stay here long-term to cooperate with us, because the success rate of completing this technology is too low, this civilization isn't willing to gamble, and we don't have enough trust to carry out thousands of years of long-term cooperation."
The Half-sphere people knew what was going to happen in the Milky Way, staying in one place long term was not safe.
